I ordered mine......
I ordered mine from e-bay a few years back. I previously had an 8 foot dink and now my inflatable dink is about 10'6", I think. I would not recommend anything smaller. A 10-6 is not as big as it sounds, take away the pontoon sections that extend behind the stern and the thickness of the floatation tubes up forward and there aint that much room left over. You have to sit a tad forward of the stern to steer properly, have room for the gas tank, a small cooler, a small anchor and you have enough room left over for one more person besides yourself. I had a Catalina 30 and i used the Martek Dinghy Davits...which are great. I had mine setup so that I could suspend the dink, tow it behind in the normal towing position, tow it with bow raised and points dragging or stern up and bow dragging. When leaving dink, i would undo the motor and lay it inside the dink, raise it and remove O/B . When dropping in the water, I put O/M inside dink, lowered dink, got into dink and then set O/M in place. I used one of my halyards to raise dink onto front deck if I wanted it there.I bought a 4HP motor because of weight. Am sorry I did. The dink just misses going into a plane. I think a 6HP would do thr trick. Again, keep O/M weight in mind. Its not easy to maneuver it when bouncing around.Good Luck in whatever you decide.
